IMPROVEMENT IN MECHANISMS FOR OPERATING RAILWAY TRANSFER-TABLES.

Specification forming part of Letters Patent N0. 146,685. dated January 20, 1874; application filed I September 25, 1873.

motion, and for increasing the adhesion of the cable.

In the accompanying drawing, Figures l, Sheet` l, show a plan view of the drivingwheels. Fig; 2, Sheet 1, shows a side view of the same. These views show the stationary driving-gearing with which our present invention is connected. Fig. 3, Sheet 2, is a plan, showing the arrangement of one side of the car or carriage, the other side being a duplicate in all its parts. Fig. 4, Sheet 2, is a side view of the same. Fig. 5, Sheet 2, is an end view. These figures, 3, 4, and 5, represent our present invention. Fig. 6, Sheet 3, is a general plan, showing the car or carriage, the relative position of the wheels, and the arrangement of the endless rope or cable.

A is the car or carriage, which is constructed in any desired form. B B represent the track on which the carriage runs. C is an endless rope, belt, or chain. E are drivingwheels, which are actuated from the engine. All these wheels are geared together and provided with pulleys, around which t-he endless rope or belt passes in the manner shown, and by which the slipping of the same is prevented, and the aggregate adhesion of the rope to all the wheels is secured. F- represents a loose pulley or idler, around which the endless rope or belt runs freely at the other eXtreme of the railway. The axis of said wheel or pulley revolves in a suitable longitudinal slide, and is provided with appliances for tightening the cable. G represents pulleys, of any desired number, having grooves in their peripheries to suit the form of the cable used. These pulleys are rigidly secured to the shafts H, whichrevolve in bearings attached to the with their faces bearing against the sidesof the rails, to retain the carriage in position on the track, instead of flanges.

placed and revolved on suitable axles, for the purpose of guiding the rope upwardand conducting it in a horizontal line into the groove of the rope-wheels. I

The arrangement of the wheels, shafts, gearing, 85o., on the other side is a duplicate in all its parts of the above, as shown in Sheet 3.

The operation is as follows: The cable is supposed to bein continuous motion, actuated by means of a belt on the pulley S, carrying the pulleys G, shafts H, gear-wheels I, and friction-wheel J around freely, while, at the same time, the carriage remains at rest; but c when the brakes are applied to the' frictionwheel J on one side of the endless cable, the brakes will allow the wheel J to slip, with constantly decreasing speed, until the inertia of the carriage is gradually overcome, when it will be held firmly, the whole train stopped,

and the carriage will then move along at the same speed and in the same direct-ion as that.

side of the cable on which thebrakes are applied, while, at the same time, the pulleys and other attachments on the opposite side of the cable will continue to revolve freely. former are released and the brakes are in turn applied to the latter, the operation will be reversed, and the carriage will move in an 0pposite direction.

This is essentially a labor-saving appffiratus,`
